How many reputation points do you need to create a new tag in HCC?

[#1]

New tags can only be created by those users who have 50 or more reputation points. If you need one and you don’t have enough points send an email to @Mark Herring .

Few guidelines:

• No more spaces in tags
• Tags can only have 25 characters

Original answer:

This is the closest i could get. 
Doesnt talk about the >= points, but tells about the guidelines.

May be we need to go via submitting Tag request, if deemed necessary.
